From: Simon Glass Date: Wed, 22 Feb 2023 19:17:03 +0000 (-0700) Subject: bootflow: Rename bootflow_flags_t X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=4f806f31fc29b30f06bd13abe44a1d3649d480e5;p=u-boot.git bootflow: Rename bootflow_flags_t These flags actually relate to the iterator, not the bootflow struct itself. Rename them.
